The Provided Group Cell Component is the default Cell Component for showing expand and collapse functionality.

The Provided Group Cell Component covers almost all use cases.

## Configuration

The key for the provided Group Cell Component is `agGroupCellRenderer`.

The Cell Component takes many parameters to configure it. Here is an example of a Column and its configuration:

```js {% frameworkTransform=true %}
const gridOptions = {
    columnDefs: [
        // column definition configured to show group values with the cell renderer set to 'group'
        {
            showRowGroup: true,
            cellRenderer:'agGroupCellRenderer',
            // provide extra params to the cellRenderer
            cellRendererParams: {
                // turn off the row count
                suppressCount: true,
                // turn off double click for expand
                suppressDoubleClickExpand: true,
                // enable checkbox selection
                checkbox: true,
                // provide an inner renderer
                innerRenderer: myInnerRenderer,
                // provide an inner renderer
                innerRendererParams: {foo: 'bar'},
                // provide a footer value getter
                footerValueGetter: myFooterValueGetter
            }
        }
    ]
}
```

The full set of parameters for the group cell renderer are defined on `IGroupCellRendererParams` and include:

Below shows an example of configuring the provided Group Cell Component. The example setup is not realistic as it has many Columns configured for showing the groups. The reason for this is to demonstrate different Group Column configurations side by side. In your application, you will typically have one Column for showing the groups.

The example is built up as follows:

* The data is grouped by two Columns: **Type** (one of 'Fiction' or 'Non-Fiction') and **Country** (a country name, eg Ireland or United Kingdom).

* The Column **'Country Group - No Renderer'** configures the grid to put the 'Country' group data only into this Column by setting `showRowGroup='country'`. All rows that are not this group are blank. There is no Cell Component (`cellRenderer`) configured, so the grid just places the text for the group into the Cell, there is no expand / collapse functionality.

* The Column **'All Groups - no Renderer'** builds on before, but adds all groups by setting `showRowGroup=true`. This gets the Column to display all groups, but again no Cell Component so no expand / collapse functionality.

* The Column **Group Renderer A** builds on before, but adds the provided Group Cell Comp with `cellRenderer='agGroupCellRenderer'`. The values are exactly as per the previous column, except now we have expand and collapse functionality.

* The Column **Group Renderer B** builds on before, but adds `field=city` so that the city is displayed in the leaf nodes in the Group Column.

* The Column **Group Renderer C** builds on before, but adds the following `cellRendererParams`:

  * `suppressCount=true`: Suppresses the row count.
  * `suppressDoubleClickExpand=true`: Suppress double click for expanding.
  * `checkbox=true`: Adds a selection checkbox.
  * `innerRenderer=SimpleCellRenderer`: Puts custom rendering for displaying the value. The provided Group Cell Component will take care of all the expand / collapse, selection etc, but then allow you to customise the display of the value. In this example we add a border when the value is a group, and we set the colour based on whether the cell is a leaf node or not.

If you require functionality that is not provided by the provided Group Cell Renderer then consider providing your own [Custom Group Component](./group-custom-group-comp/).
